The isoscalar exchange currents for nuclear systems consisting of two and three nucleons are studied in the framework of Skyrme's model for hadrons. For the deuteron the authors obtain an isoscalar form factor almost identical with that of meson-exchange models; the zero in the single particle form factor near q/sup 2/ {approx equal} 20 fm/sup -2/ is drawn to q/sup 2/ {approx equal} 19 fm/sup -2/, the form factor being also increased in the momentum-transfer range q/sup 2/ > 20 fm/sup -2/. The isoscalar exchange current in the system of three nucleons draws the zero in the form factor towards values closer to experimental ones, similar to other meson exchange models. In addition to two-nucleon contributions to the current, they also treat three-nucleon terms in the A = 3 system.
